16-BIT MICROPROCESSOR
DESCRIPTION
The
µ
PD70433 (V55PI) is a microprocessor in which a 16-bit CPU, RAM, serial interface, parallel interface, A/D
converter, timers, DMA controller, interrupt controller, etc., are integrated in a single chip.
The V55PI is software-compatible with the
µ
PD70320 and 70330 (V25
TM
and V35
TM
) single-chip microcontrollers. The
V55PI provides a migration path from the V25. It offers higher-level functions and higher performance, and is particularly
suitable for control of data processing systems associated with mechanical control, including printer and facsimile.
Detailed functions are described in the following user’s manuals, which should be read when carrying out
design work.

Remark
IC: Internally Connected
Notes 1. The IC (H) pin should be connected to V
DD
with an external resistor (1 to 10 k
Ω
).
2. The IC (L) pin should be connected to GND with an external resistor (1 to 10 k
Ω
).
3. No connection should be made to the OPEN pin.
